SQL 地理 河流移除
如何从 GeographyCollection 中删除“孔”/线串/.etc？其次，如何连接不与一个多边形相交的 MPolygons？
我们将邮政编码汇总到地理地图上，但形状上有洞。研究了这个那个，但我还没有找到去除内孔的好方法。
ConvexHull 创建了一个时髦的形状，但这也不是我们真正想要的。目标是使该区域“贴合”在一起，以便人类可以在地图上查看。
.Reduce 有帮助，但它并不能删除所有内容。我真的只想只有当有 2 个多边形彼此相邻时才会出现具有微小（小）ConvexHull 的外层信封。
想法？重定向？
How do you remove the 'holes'/linestrings/.etc from a GeographyCollection? Secondary, how do you join MPolygons that don't intersect into one polygon?
We have a roll up of zipcodes to a geographic map, but we have holes in the shape. Researched this and that, but I have not found a good way to remove the inner holes.
ConvexHull creates a funky shape that is not really what we want either. The goal is to have the region 'fit' close together so they are human-viewable on a map.
.Reduce helps, but it does not remove everything. I really just want the outer envelope with minute (small) ConvexHull occurring only if there are 2 polygons next to each other.
Thoughts? Redirects?
